Marshall's Research


Week 14:

Completed Protein Characterization, FPLC, and FPLC protein fraction concentration

Gel Before Being Dried Inverted so lanes are actually rows. Rows from top to bottom: Sample 6,5,4,3,2,1,0, protein ladder

Dried Gel Upside Down. By looking at the Protein Bands Expression and Characterization was successful



Week 13:

Week of Thanksgiving

Week 12:

4 colonies found on plate A. 5 colonies found on plate B. Completed MasterPlate protocol. Completed Purification and Concentration. Nanodropped Elution Sample 1 and 2.

Elution 1

Elution 2

Week 11:

Fill out form to order 5 of my top ligands from cb-306-3d and hf9. Finished Ligation and Annealing. Checking for clones monday the 14th.

Week 10:

Finished Protein Expression Protocol with pellet weights of 2.51 and 2.57 grams. Ran Accepting Vector through Nanodrop

Week 9:

Sent 6 samples to the DNA core for sequencing. My sequencing results revealed that I have hollow clones without the insert I want in them. I have started the first run on all of the libraries I am supposed to virtually screen.

1LICfMJF results - the image shows that my sequence from DNA sequencing does not match my sequence from the YopH target page


Week 8:

1st Virtual Screening job submitted today. I have 2 jobs submitted and am waiting on for results. I also nanodropped my miniprep product
Colony 1

Colony 7

Colony 8

my concentrations were not high as I would like but I'm still going to send them to dna sequencing
Colony 1,7, and 8 are also the only colonies to produce bacteria during the master plate protocol

Week 7


After 2 days of incubation colonies showed up on my plates. Moved from cloning version 3 to making a master plate and growing up the bacteria I found on my plate from cloning version 3. Also finished Virtual Refresher this week, and finished my research report.

Week 6:

Did cloning Version 3. After a night incubation only one colony has grown. I'm going to incubate longer and see what happens. Cloning Version 3 didn't work see images below:

Plate A: no colonies

Plate B: 1 colony

Made the Pymol Version of my active site:

yi1 in Yoph Yersinia Pestis PDB: 2Y2F


Week 5:

Accepting Vector gel check proved that once again my accepting vector preparation failed. I found out it was due to the new enzyme requring incubation at 37 degrees and not 50

lanes from left to right: 1kb ladder, accepting vector (one faint line)


Redid Accepting Vector protocol and got the following results when I did the PCR clean up. It has two different tops of curves that show up which gives me hope that my accepting vector was successfully cut. But my gel check will confirm or deny this.

Week 4:

Nanodropped PCR^2 Results. Had Concentration of 159 ng/ul. Completed PyMol Refresher.
Started Gold Refresher. Completed Preparation of Accepting Vector.

Week 3:

Gel Checked secondary PCR and had no contamination. Worked on PyMol Refresher
which was uploaded to my student folder on google docs.

Lanes from left to right: 1kb ladder, primary pcr, secondary pcr, ladder

Week 2:

Did PyMol Lab 1 and 2. PCR^2 completed.

Week 1:

Analyzed DNA results from summer to discover that my cloning was unsuccessful.
Primary and Secondary PCR completed

6/7/11 Transformation Efficiency Results


SAM_0361.JPG
0 colonies of E. coli were found when 5 ng of plasmid pCHERRY were added to tube B




SAM_0362.JPG
1 colony of E. coli was found when 25 ng of plasmid pCHERRY were added to tube C




SAM_0363.JPG
No colonies of E. coli were found when 1 ng of plasmid pCHERRY was added to Tube A


The low number of colonies found could have resulted from using bacteria too long after they had thawed.
